ABSTRACT 

This study investigates the use of dielectric barrier discharge (DBD) plasma as a rapid surface modification technique to enhance carbon-PVA electrode adhesion on Al and Cu current collectors, correlating the improvement in adhesion strength with changes in surface wettability. Plasma treatment was performed at 10 kV and 50 W for 3 seconds in ambient air, followed by electrode coating using dip and brush coating methods. Adhesion strength measured by 180° peel testing increased by 26.3% on Al (from 25.09 ± 1.27 to 31.70 ± 1.49 N/cm²) and by 34.3% on Cu (from 27.73 ± 2.17 to 37.25 ± 2.00 N/cm²). Water contact angle measurements confirmed increased surface hydrophilicity. The greater enhancement on copper suggests that plasma–surface interactions are metal-dependent. DBD plasma treatment offers a practical, solvent-free alternative to conventional chemical surface pretreatments, with potential for integration into roll-to-roll electrode manufacturing processes.
